  • Make sure that there is no firewall not allowing TFTP for the initial code upgrade. (Enable the ports 13907 and 13910 on the firewall).
  • Make sure to enable the TFTP port 69 TCP and UDP.
  • Reset the AP to factory default: There is a pinhole button on the side of the AP3705i that needs to be held down for 5+ seconds to initiate factory default.
  • Set the MTU to 1400 and rebooted the APs.
